(01 274-45) The present invention relates to mechanism forfeeding elongated bodies to a machine and" vices for clamping the sameon' the machine and means operating in proper sequence for actuating theparts; and further, to provide improved *speciiic means for this-purposeThese and any other objects hereinafter appearing are attained by, andthe invention finds preferable embodiment in, the illustrativemechanismparticularly described in the body of this specification andillustrated by the accompanying drawings, in which:

Figure 1 is an elevational front view of mechanism for successivelyfeeding elongated bodies (as the needles or styli of a graphophone) andfor releasably clamping the same to a machine part (as to the tone armof the graphophone),

Figure '5 is a sectional view of certain parts of said mechanism takenon line 5-5 of Figure 1; W 1 Figure 6 is a sectional view of certainparts of said mechanismgtaken on line 6-6 of Figure 1;-

Figure '1 is a top or said mechanism, partially broken away and 9showing a lever sectioned on line '77 of Figure 2; a

Figure 8 is a detail view of parts of said mechanism sectioned-on line8-8 of Figure 3;

Figure 9 is a bottom end view of a vertically movable rod with connectedparts;

Figures 10, 11 and 12 are end views of a shaft and connected parts,showing the same in diiierent turned positions.

The particular embodiment of -the invention 9 illustrated by thesedrawings is employed for feeding to; and clamping in, a graphophonestone arm 1 its elongated cylindrical needles or,

styli 2. These needles in vertical position are removably held injhol'es3 circularly disposed in series in the upper'side of a carrier-4 whichis plan view of certain parts.

turnable in its bearing 5 in the upper end oi a squared rod 6 verticallyslidable in a bearing '7 in the mechanisms frame 8. In Figure lythiscarrier is shown in solid lines in its lowered position from which it israised to dotted line position to insert into the socket 9 of the tonearm the particular needle which has been brought, by a previous turningmovement of the carrier, into registration with. this'socket. The

carrier is raised to its dotted line position (Figure 1) by the turningof'a disk10 having in its inner side a cam groove 11 in which travelsthe roll 12- on an arm of the flever.13 fulcrumed at. 14, whose otherarm 15 is connected to a link 16 pivoted at 1'7 on said squared rod 6.

As seen in Figure 1, a worn needle 2 is about to be released from thetone arm and replaced. with a new needle 2 taken from the carrier. To dothis, the cycle of themechanisms operation is as follows: The 'disk 10is rotated so that the peripheral cam groove 38 moves the roll 37 onone'arm 36 0! a lever 31 (fulcrumed at 32) into the portion 60 of saidgroove 38 and thereby slides the shaft 2'7 (rotatably mounted at '61 onthe frame) toward the left hand side of Figures 1 and 3 thereby causingthe kerf 39 in the end of said shaits member 40 to engage thediametrical rib 41 on the end or head-i2 of a set screw 43. threaded inthe tone arm and extending into its socket 9 and into engagement withtheneedle 2 to clamp the same therein. The shaft 2'7, act-" ing as ascrew driver, is rotated to turn said screw sufllcientlyto release thisneedle 2 by means of the rotation of said disk on whose crank wrist pin25 is carried a rack 24 meshing with a gear 26 to turn said. shaft 2'1.The

needle 2 thus released falls 'out of socket screw 43 reversely. and intobinding engagement with the needle which has just been inserted into thesocket, whereupon said disk's further turning movement causes the roll12 to pass into the dwell 18 and. restores the parts to initial positionshown in solid linesin Figure-1.

For the purpose of cushioning-the action, the gear 26 has ap'in 29 andthe shaft 27 hasa pin 30 Connected by a coiled spring 28. Normally thesepins are in the abutting relation The turning movement of the shaft withits member 40 in contact with the screws rib 41, but before the rib 41is in alignment and engagement with the kerf 39 is thus permitted, andis also permitted by the,axial movement of said member splined to saidshaft by its screw key 44 engaging in the shafts longitudinal groove 45,said member being pressed outwardly by the spring 46. At a point in thelowering movement of the carrier, one'of the circularly disposed teeth19 on its under side engages the pawl arm 20 of a bell crank lever 21fulcrumed at 22, and the continued downward movement of the carrier insuch engagement causes the carrier to turn a suflicient distance tobring the next succeeding needle 2 held thereby into registration withsaid socket for insertion, thereinto on the next rising movement of thecarrier. The carrier is held against reverse turning by the detent 51pressed into engagement with one of said teeth by the spring 52.

The disk 10 may be rotated to operate the said mechanism by any suitablemeans, as by connections with the driving or operating means of thegraphophone or other machine to which said mechanism is applied, and atintervals for replacing such worn elongated bodies, as the worn needlesof a graphophone. shown is in the form of a gear meshing with a drivinggear 49. The rack 24 bears slidably in a turnably mounted block 50. Thewrist pin 25 is carried by a block 53 slidable to adjusted positions' ina diametrical groove 54 in the disks portion 23 and held in suchpositions by the nut 56. When a needle 2 is released from said socket itfalls into a chute 47. This chute has a springable upper end or trough48 (shown in solid lines in its normal position) in which the discardedneedle 2 is guided into the chute.

Thereafter, the rising movement of the carrier to insert a new needleinto the socket slides at its edge alongsaid end 48 and springs it todotted line position (shown in Figure 1) out of the way of said newneedle. erative movement its tone arm swings past its position in whichthe needle is inserted into its .socket and the carrier is lowered topermit said "end 48 to spring back to its solid line position.
